MINERS CAP LAMP CONNECTION.

Application led February v16, 1922. Serial No. 537,091.`

/ 1o @ZZ w from t 'may concer/n Be it known that l, @Hannes H. Mnis'rnn, a citizen of the United States, residing at Bellaire, in the county of Belmont and State of Ohio, have invented new and useful lmprovements in Miners Cap and Lamp Connections, of which the following is a speciiication.

The object of my said invention is the provision of a simple and strong construction for the detachable connection of a lamp to a miners cap, and one which will permit of ready connection and disconnection oii the lamp with one hand, and this without liability or the lamp being casually disconnected and displaced or moved when the miner stoops or otherwise moves his body or head.

To the attainment or' the foregoing, the invention consists in the improvements Vas hereinafter described and definitely claimed.

In the accompanying drawings', forming partof this specification Figure 1 is aside elevation showing my improvement in use.

Figure 2 is an enlarged vertical section of the same.

Figure 8 is a detail transverse section taken in the plane indicated by the line 3-3 of Figure 1.

Figures 4 and 5 are perspectives of the body plate and reeniiorcing plate, respectively, of the improvement.

Figure 6 is a perspective of the spring.

Figure 7 is a detail perspective of the lamp member.

Similar numerals designate corresponding parts in all of the views of the drawings.

In accordance with my invention the lamp 1, Figures 1 and 2 is provided at its back with a member 2, preferably of sheet-brass, fixed at its ends to the lamp.

The said member 2 is equipped at 3 with a rearwardly projecting stud which includes a shank 4 and a head 5, both in rear or the vertically-disposed portion of the member 2 and appropriately iixed to said portion. The head 5 shown in Figures 2 and 7 is rounded atits rear side and fiat at its forward side while the shank 4 is o'r' rectangular shape in cross-section,

The cap 6 shown in Figures 1 and 2 is provided with a visor 7 and is otherwise of the ordinary miners cap construction or of any other type compatible with the purpose of my invention.

rIhe cap ortion of my improvement comprises a bo y plate 8 and a reenforcing plate 9 both of which are made of appropriate sheet-metal, galvanized when deemed expedient. The plate 8 comprises an intermediate, upright portion that rests against and is attached at 10 to the iront of the cap body, an upper horizontal portion that rests on the cap crown and is connected thereto at 11, and a lower inclined portion that rests solidly on the visor 7 and is attached atY 12 to the same. For the stiening of the body plate 8 the longitudinal edges of the same are preferably folded forwardly and inwardly as designated by 13. In the center oi' the apex of the angle formed by the intermediate and upper plate portions is formed an opening 14 suiiiciently large for the vertical movement through the same of the stud head 5, and in the intermediate plate portion is formed a contracted slot 15 0i? a size to snugly receive and seat and hold the stud shank 4. yThe angular reenforcing plate` 9is interposed and secured between the edge portions 13 of the plate 8, andis provided with an opening 14X and a depending slot 15 ,7re'gisteredy with and corresponding in size to the opening 14 and slot 15, respectively, of the plate 8.

Fixed at 16 to and carried at the back of the intermediate portion of the plate 8 is the s-hank 17 of a curvilinear spring 18 positioned in rear or" the openings 14 and 14 and the slots 15 and 15X as clearly shown in Figure 2.

Vertical movement of the lamp 1 and its member 2 of the cap wearer is all that is necessary to couple said stud from the plates 8 and 9. Manifestly when the stud head 5 is moved downwardly through the openings 14, 14", and the rectangular stud shank 4 is seated in the slots 15, 15X, the lamp will be strongly connected to and supported by the cap without liability of casual disconnection of the lamp or sidewise movement thereof. To detach the lamp from the cap it is simply necessary for the miner t0` reach up with one hand and move the lamp straight upwardly, relative to the cap, when the disconnection will be effected by the upward passage of the stud out of the slots 15, 15X, and through the openings 14, 14X.

When the lamp is connected to the cap as appears in Figure 2, the spring 18 strongly though yieldingly presses the flat couple the stud 4-5 to or un-v Y. ferred Iembodiment of my invention',l in ordeiwto impart a full, clear and exact underf 4standing of thelsaid` embodiment. I do not side of thestud head `5 against the rear side of the plate 8 to render the connection tight and at the same time the said spring 18 holds the stud against upward "movement, some little stress being necessary4 to move the stud home in attaching the lamp and to move thestud upwardly for the disconnection of the lamp.

ff, I have entered Iinto a detaileddescription of the construction and relativearrangement of the parts embraced in -tliepresent and predesire, however, to be understood as con- ;H `fining myself ytothe said specific construcl ,tion .and 'relative arrangement of parts invof V my invention 1 claims. v

' asinuch as inthe future practice of the in!` :.vention variousjchanges and modificationsl may be' made such'as fall within the scope as defined in my appended.

Having described my inventionpwhat I enla-im and desire to secure by Letters-Patent, isz-l l1. A' cap` and lamp connection :comprising i. a bodyy plateattached to a :cap and having v .j an uprightzportion and :a top` portion extending rearwardly at an angle to the upright portion and yalsohaving an opening in the apex of the angle formed by said y portions, anda-slot formed infthe upright 'portion and .extending downwardly 4from `Said opening, aicurvilinear spring arranged .35

back'of said slot and carriedby the upright portion of the plate, and la member carried bly a lainp and having an upright portion 'to rest against the upright portion of the body plate and also having a rearward'lyextending stud with a shank, of

rectangular form in cross-section, and a head flatlat its forward side and rounded at its rear side.

" "'2. A capand lamp connection comprising a body plate attached to a cap and having an upright portion and a top portion extending rearwardly at an angle to the upright portiony and also having an opening in'the apex of the angle formed by said portions, and a slot formed in the upright [portion andextending downwardly from said opening, a curvilinear spring arranged back 4of said kslot and4 carried by the upright portion of the plate, and a member carried by ak lamp and having an upright portion to rest vagainst the upright portion of the body plate and also having a rearwardly extending studl with a shank, of

rectangular form in crossleseotion, and a oHAs. H. MEISTER.
